granite-embedding-97m-multilingual-r2 -- ONNX for Teradata BYOM

This repository hosts an ONNX-converted version of the upstream model ibm-granite/granite-embedding-97m-multilingual-r2, packaged for the Teradata Vantage mldb.ONNXEmbeddings BYOM function. It is not the original PyTorch model -- only the inference graph and tokenizer needed for in-database embedding generation.

What's different from upstream:

Format: ONNX (opset 14, IR version 8 -- BYOM 6+ compatible), produced from the upstream weights with architecture-aware post-processing baked in.
Precision: dynamic int8 quantization. See the variants table below for what is shipped for this model.
Pooling and post-processing: this graph emits the raw sentence_embedding tensor. Pooling rule is cls.
Verification: every variant's cosine fidelity vs. the upstream PyTorch reference is recorded on a fixed FLORES-200 sample. Numbers may not generalize to your data.

Quantization variants

This repository ships the following variants. Quality numbers are measured against the upstream PyTorch reference on a fixed FLORES-200 sample. The Size column is the on-disk size of the ONNX weight file in megabytes (MB, 10^6 bytes).

Variant	Size (MB)	p50 cosine	R@1
`fp32`	390.1	1.000000	—
`ffn_skip`	161.7	0.999242	0.934

How to read the quality columns:

p50 cosine is the median cosine similarity between this variant's embeddings and the fp32 ONNX reference, computed over a fixed evaluation set. Higher means closer to the unquantized model; 1.0 is identical.
R@1 is top-1 retrieval consistency: if you use this variant as a search index, R@1 is the fraction of queries that get the same nearest neighbor as the fp32 reference would. Higher is better.

Notes:

fp32: full-precision reference. Useful for an accuracy ceiling, but BYOM users almost always want one of the int8 variants for in-database scoring -- they are 3-4x smaller and load much faster.
ffn_skip: dynamic int8 with the feed-forward (FFN) MatMul layers kept in fp32, while attention and projection MatMuls stay quantized. The FFN layers are where most of the quantization error in transformer blocks concentrates; leaving them in fp32 recovers most of the quality loss for a modest size increase. The artifact is roughly 3x smaller than fp32 (larger than the per_channel int8 sibling). Ship this variant when retrieval quality is the priority and the per_channel drift on your workload is unacceptable.

Quickstart: using this model with Teradata BYOM

Requires Teradata Vantage with BYOM 6+ (mldb.ONNXEmbeddings).

python

import getpass
import teradataml as tdml
from huggingface_hub import hf_hub_download

repo_id   = "Teradata/granite-embedding-97m-multilingual-r2"
model_id  = "granite-embedding-97m-multilingual-r2"        # arbitrary, used as the BYOM model_id
onnx_file = "onnx/model-ffn_skip.onnx"

# 1. Download the ONNX + tokenizer for the chosen variant.
hf_hub_download(repo_id=repo_id, filename=onnx_file,       local_dir="./")
hf_hub_download(repo_id=repo_id, filename="tokenizer.json", local_dir="./")

# 2. Connect to Vantage.
tdml.create_context(
    host=input("host: "),
    username=input("user: "),
    password=getpass.getpass("password: "),
)

# 3. Load model + tokenizer into BYOM tables (one-time per model_id).
tdml.save_byom(model_id=model_id, model_file=onnx_file,
               table_name="embeddings_models")
tdml.save_byom(model_id=model_id, model_file="tokenizer.json",
               table_name="embeddings_tokenizers")

Then call mldb.ONNXEmbeddings against an input table whose txt column carries the strings to embed:

sql

SELECT *
FROM mldb.ONNXEmbeddings(
    ON (SELECT id, txt FROM your_input_table) AS InputTable
    ON (SELECT model_id, model FROM embeddings_models
         WHERE model_id = 'granite-embedding-97m-multilingual-r2') AS ModelTable DIMENSION
    ON (SELECT model_id, tokenizer FROM embeddings_tokenizers
         WHERE model_id = 'granite-embedding-97m-multilingual-r2') AS TokenizerTable DIMENSION
    USING
        Accumulate('id')
        ModelOutputTensor('sentence_embedding')
        OutputFormat('FLOAT32(384)')
        OverwriteCachedModel('*')
) AS t
ORDER BY id;

Pooling rule cls is applied inside the converted ONNX graph -- the output tensor named above already contains the pooled, post-processed embedding vector.
